Hub Oil Level

[dhirocz]

The carrier I'm leased to is trying to change from 'oil bath' style hubs to greased hubs. I am not a fan of the greased hubs. I know why they like them, less chance of an OOS condition if you blow a seal, it won't drench your shoes in oil...but the rolling resistance on the greased ones SUCK. Half of it is probably them setting the wheel bearings too tight.

I've noticed 1/2 mpg difference between these trailers unloaded. It's rediculous. The worst ones I find often low on air as well. Ugh.
